I am very new to Visual Studio/C# (although I have a good deal of C and C++ knowledge) and it seems that I am missing something since I cannot figure out how to do this and I am getting frustrated (this is supposed to be a simple project).

I am supposed to write a DLL with a class that has a method accepting two strings and returning one.

This dll will be used by a windows form application. I will be entering two strings on the form, clicking a button and the button will call the DLL which will then return another string into a text field on the form.

The return string will consist of a couple of other strings (assembly version number major/minor, etc.) appended to one of the original strings passed to the dll (ie., the other string passed in will be ignored).

My problem is I don't know where to start. Is there any way I can do this without string manipulators? I don't think I am supposed to use them. If I use Console.WriteLine, I am guessing this will not return the message to the form, but write it to the console?

Thanks for any help you can provide.
